Background
The treadmill hadn't been used in roughly a year, when it was powered up again everything lit up and seemed ok until the Start button was pressed. Something must have short out, there was a burning smell and it tripped the main breaker in the house.

Let me first just say I have a basic understanding of electronics but like to tinker with things and repair them myself if possible.

Now the treadmill still turns on and lights up but there's no power to the motor. So far I've tested the motor itself with a cordless drill battery and it worked ok. Fuse tested and working. Control board has been taken out and from a visual inspection I can see some burnt/blown resistors. See pics

Would this board even be repairable? Just to add, the treadmill was pretty filthy when I opened it up, looks like it was infested with rat faeces which is what might have caused all of this
